Application filed February 21, 1912. Serial .No. 678,090.

To all whom it may concern:

Be it known that I, NAPOLEON DEMERS, a subject of the King of England, residing at Sherbrooke, in the Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Bobbin- BoringMachines: and'I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of refer,- ence marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for boring and reaming warp and filling bobbins and comprises a simple and eflicient apparatus of this nature having various details of construction and combinations and arrange ments of parts which will be hereinafter fully described. shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a front view of my invent-ion. Fig. 2 is a rear elevation. Fig. 3 is a top plan view. Fig. 4 is a side View of the kickout device. Fig. 5 is a sectional view on line 55 of Fig. 1. Fig. 6 is a detail view of the automatic tripping mechanism. Fig. 7 is a detail view of the bobbin holder. Fig. 8 is a detail view of one of the bobbins. Figs. 9 and 10 are detail. views of parts of the apparatus. Fig. 11 is a sectional view through one of the bobbins after having been bored by my apparatus. Fig. 12 is a detail view of a spring-pressed pivotal hook designed to prevent the endless carriage from travel in one direction. Fig. 13 is a detail View in elevation. Fig. 14 is aperspective view of an automatic feeding device, and Fig. 15 is a front elevation of said modification. I

Reference now, being had to the details of the drawings by numerah'l designates the frame of the apparatus which has a metallic top 2 held securely to the frame bymeans of bolts 3. Journaled in suitable bearings bare the shafts 5 and 5, upon each of which is a pair of flanged wheels 6. driving wheel. designated by numeral 7. 1s fixed to a shaft 7, and 8 is a belt passing about the same socket member 15.

and adapted to be driven from any source of power and forming means for driving the apparatus. An endless carrier made up of pivotal plates, each designated by numeral 9 and one of which is shown clearly in Fig. 6 of the drawings, travels about the flanged wheels 6 and each of said plates is provided with integral eyes 10 upon corresponding edges and each carries adjustable rods 11 with eyes 12 at one end and threaded at their outer ends. The rods pass through registering apertures in the plates and are held in adjusted positions by means of the nuts 13, as shown clearly in Fig. 6 of the drawings. By the provision of these adjusting features, it will be. noted that any wear which may come upon the chain made up of the pivotal plates will be readily taken up.

Fixed to each plate9 is a spindle receiving bracket member 14 having a tapering recess or socket 15 therein, designed to receive one end of the bobbin 16 to be longitudinally bored. Each plate also carries, at the end opposite, to that on which the socket member 14 is mounted, a bracket member 17, having lugs 18 rising therefrom, each provided with an aperture.

Said bracket members 14, it will be noted, have upright portions which are apertured as at- 14 and rods 18' pass through the registering apertures in the bracket members carried at the opposite ends of the plates.

Mounted upon each pair of rods 18', it being noted that each plate carries two of said rods, are the bobbin-receiving heads 19, which are shown in detail in Figs. 9 and 10 of the drawings. Each head 19 has a series of inclined fingers 20 projecting therefrom which hrwe sharp knife edges and are designed to engage frictionally one end of a bobbin in the manner shown clearly in Fig. 3 of the drawings to hold the same in the Each bobbin receiving head 19 is provided with a shank portion 21 held adjustabLy by means of a set screw 22 in the bracket member 23, a detail of which is shown in Fig. 10 of the drawings, and which has laterally extending arms 24tapertured at 25 for the reception of the rods 18 upon which they are mounted. Set screws 24 pass through threaded openings in said arms and are adapted to engage the rods 18 to hold said bracket members 23 in adjusted positions. Coiled springs 26 are mounted upon the rods 18 and have corresponding ends fastened to the bracket member 23. Said springs are also fastened to the bracket member '14 so that, as longitudinal movement is imparted to the rods 18' to the right, the springs will be under tension and will serve to return the rods to their normal positions.

Mounted to have a longitudinal, reciprocating movement upon the frame is a series of carriages, shown in rear elevationin Fig. 2 of the drawings and designated respectively by numerals 28, 29 and 30. Each of said carriages has its opposite edges grooved and adapted to receive a rib 31 to guide the carriage in its back and forth movement. Guide ribs 32 adjustable by screws 33 mounted in threaded apertures in the frame, engage respectively the. outer edges of the side carriages 28 and 30. The carriage 28 bears the bit shafts 34 and 35, bit sockets 37 and 38 and bits 39 and 40. The carriage 29 bears the bit shafts 41, 42 and 43, suitable bit sockets and the bits 44, 46 and 47. The carriage bears the single bit shaft 48, the socket 49 and a reamer 50. Each bit shaft carries a pulley 52 to accommodate belts 53,

for which there are also overhead pulleys not shown but which have a swinging movement on suitable hangers to allow for the longitudinal sliding reciprocation of the carriages.

Projecting from the under surface of the carriage 28 is a lug 28 upon which a roller 54 is journaled and upon a lug 29 of the carriage 29 is mounted a similar antifriction roller 55, and upon the carriage 30 is a lug 30' having an anti-friction roller 56.

Jonrnaled in suitable bearings 57 upon the frame and as shown clearly in Fig. 2 of the drawings are the three shafts, designated respectively 58, 59 and 60, to which respectively are fixed the cylinders 61, 62 and 63. Each of the cylinders is provided with two spirally shaped ribs 64, shown in Figs. 3 and 5, and it will be noted upon reference to said figure that the meeting ends of said ribs overlap each other and are spaced apart and the adjacent edges of said ribs are parallel for a short distance in order to allow the cylinder to cease momentarily the feeding movement of the carriage at a predetermined moment while the spindles are being advanced one step in the operation of the apparatus. The shaft 58 has a gear wheel 65 fixed thereto which is in mesh with a similar gearwheel 66 upon the shaft 59, and

67 is a gear wheel upon the shaft 60 intermeshing with the gear wheel 66, and a pinion wheel 68 is fixed to the shaft 7 upon which the driving wheel 7 is mounted, thereby affording meanswhereby the power may be applied to drive the various cylinders in the directions indicated by the arrows thereon.

Mounted upon and adapted to'rotate with the shaft 5 is a star wheel 70, a pawl 71, shown in Fig. 2 of the drawings, being pivotally mounted upon a pin7 2 carried by the arm 73 upon the frame and serving to hold said star wheel from rotation in one direction.

Fixed to the disk 74, which is mounted upon and rotates with the shaft 59, is an arm 7 5 having an anti-friction roller 76 at its free end which, at every revolution of the disk, is adapted to contact with one or another of the fingers of the star wheel for the ment thereto, sufficient to cause the bobbin to travel from the position in ali'nenient with. one bit to a position in alinement with the next adjacent one.

In order to hold the bobbins securely while being operated upon by the, bits, I provlde the following mechanism, illustrated in Fig.

12 ofthe drawings and consisting of the spring-actuated hook 76 mounted upon apivot. 77, upon the frame and which lever has one end thereof connected to the shaft 5' by a coiled spring 78. As the chain advances in one direction. the free end of the hook comlng in contact with one or another of the plates of the endless carrier will be depressed to allow the plate to pass over the hook portion, after which thespringwill throw the hooked end up against the edge of the plate. Simultaneously with the hook springing back against one edge-of the plate, the endless carrier, made up of the plates pivoted together, will come to rest and the carriages containing the bits, which are con tinuously rotated by the belted connections, will be fed forward in the manner shown and described.

Mounted to have a longitudinal movement upon the carriage carrying the rotatable bit carrying shafts 34 and 35 is a rod 34' upon which are mounted the collars 35' and 36', the former being, held by a set screw behind the bearing blocks 36 in which the rear ends of the shafts 34 and 35 are held, while the other is in advance of the bearing blocks in which the forward ends of the bit carrying shafts 34 and 35 are journaled. T he forward end of the rod 34 has a cam shaped edge 87 adapted to be moved frictionally in contact with one of the lugs 80, shown in dotted. lines in Fig. 6 of the drawings, projecting from the lower surfaces of the plates 9 to hold the endlesscarrier rigidly while it rests and while a bobbin is being bored. It will be noted that, at each forward longitudinal movement of the rod, 34, the cam edge thereof will conie into contact with the projection 80 and hold the plate upon which a bobbin is mounted from movement in one direction, while the springpressed hook before described will engage the opposite edge, thus securely holding the carrier momentarily while the bits are fed forward with the View of boring a longi tudinal hole therein.

A tread member, designated by numeral 81, is pivotally mounted upon a pin 82, shown in Fig. 1 of the drawings, and a bar 83 is pivotally connected tothe shank por tion of the tread member and has a weighted member 84 mounted thereon. The upper end of said rod 83 is pivotally connected by a pin 85 with an angle lever 86, pivoted upon a pin 86, and which angle lever has a transverse plate 87 secured thereto adapted, when the tread member is depressed, to contact with the ends. of two of the rods 18 mounted upon one of the plates of the end less carrier for the purpose of throwing the socket member 19 back to receive the end of a bobbin-to be adjusted upon the plate. When pressure is removed from the tread,{ the weight'will tend to return the transverse plate 87' to its normal position.

The detailed mechanism for releasing the bobbin after the bore of three different diameters has been formed therein is shown in Fig. 4 of the drawings and in which I have illustrated a bar 88 which is fastened to the carriage 30 and has an aperture at one end to receive the rod 89, threaded at 90 to receive the nuts 91 and 92, provided for adjustment to limit the longitudinal movement of said rod 89. The forward endof the rod 89 is pivotally connected at 93 with one end of the lever 94 which passes through .a slot 95 in the bar 96. The bar 97 is fastened to the frame of the. apparatus and theflever 94 is pivotally connected therewith through the medium of the link 98. The bar 96 is provided with a cross plate 99 at one end thereof, which is of sufficient length to come opposite and contact with the adjacent ends of two of the rods 18, which pass through the apertures in the plates upon the endless carrier. An angled rod 100 is mounted upon a pin 101 upon the bar 96 and is connected by means of a spring 102 with the bar member 97 and, when the carriage moves forward, the angled rod 100 will assume the position shown in dotted lines in Fig. 4 and in its movement the spurs 103 at the end ofsaid angled rod will engage the bobbin and remove the same from the socket;

In Figs. 1 1 and 15, 1 have shown a mechanism for feeding bobbins automatically from the hopper to the endless carrier, in which the hopper is designated 105, to the bottom of which are fastened resilient hook fingers 100 adapted to support a bobbin as it falls from the hopper and which bobbin is automatically gripped by the socket member 107 and centering member 108 and fed forward by the carrier. The bobbin is gripped by the following mechanism: Bearing members 107 are provided with apertures for the reception of the sliding rods 110 and said bearing member 107' carries the socket memberv 107. A bearing member 109 is fixed to the rods 110 and the centering member 108 is movable .within the bearing member 109. A cam-shaped memher 112 is adapted to be fixed to a bracketupon .the frame and in the paths of corresponding projecting ends of the rods 110. As the first of t-he'two rods-carried by each member 107. comes in contact with the cam member, both rods will be moved longitudinally as each set of rods is fastened to a bearing member 109, thus causing the latter and the centering member 108 to move therewith. After the first rod passes by the cam, the second rod will still hold the centering member back to the position shown in Fi 14 of the drawin s allowin am le 1') D H p time for the bobbin to fall from the hopper upon the springs 106. After the second rod 110 passes by the cam, a spring 111, which is mounted upon one of the rods 110 and put under tension as the rods 110 are moved in one direction, will return the rods and the centering member 108 to their normal positions. The centering member coming in contact with the bobbin 16 will push the same into the socket member 107, thus securely holding the same as it is fed forward by the carrier. It will be noted upon reference to Fig. 14 of the drawings that a cam member 112 is fixed to the frame of the apparatus and is in the path of one end of the rod 110, and, as the latter comes in contact with the cam member, the rod will be given a longitudinal movement and throw the centering head back and, after the end of the rod has passed by the cam member, the centering member will return to its normal position and grip one end of the bobbin.

In the operation of the modified form, it will be noted that the bobbins will fall by gravity singly upon the resilient fingers and be held until gripped and fed forward in the manner described.

' In operation, the operator by pressing upon the tread member will cause the crosspiece'87 to move longitudinally two of the rods 18 and throw back the socket member carrying the head 19 to allow a bobbin to be bored to be inserted with one end in the socket member 15 and its other end engaged by the fingers of the socket member 19. Anintermittent motion is imparted to the carrier by means of the fingers of the inner star wheel 70 coming in contact with the lugs 80 on the under side of the plate 9, said wheel 70' being fixed to the shaft 5 which is driven by the star wheel 70, which in turn is driven by means of the antifriction rollers 70 mounted upon the arm 75 coming in contact with one of the spurs of the star wheel at each revolution of the wheel carrying said arm 75. During the interval between the engagements of the roller 76 with the star wheel 7 to advance the endless bobbin carrier, the bit carriages are advanced and retreated by the cams on the revolving cylinders 61, 62 and 63, engaging with the rollers depending from the carriages. It will be noted that the first bit 39 bores a hole of a certain depth, the next bit 40 bores the hole in the same bobbin after the latter comes in alinement therewith still deeper and the third bit 44 bores through the end of the bobbin with a bore of smaller diameter than made by the bits 39 and 40. The

bits 46 and 50'wi1l extend through and clear out any ragged edges which might remain within the bore of the bobbin. The last bit 51 constitutes a reamer and is provided for the purpose of reaming out one end of the bobbin, as shownclearl y in Fig. 11 of the drawings.

W'hena bored bobbin comesin alinement with the cross-piece 99, shown in Fig. 5 of the drawings, the bar 96 will be given. a longitudinal movement through the medium of the connections with'the bar 88 upon the carriage and cause the rods 18' to be moved against the tension of the springs thereon and thereby release the socket member 19 from the bobbin. Simultaneously with the imparting of a longitudinal movement to the rods 18, the spurs 103 at the end of the curved bar 100 will move down to the position shown in dotted lines-in Fig. 5 and remove't-he bobbin from the socket 15, a nd, when the carriage returns to its normal position, the parts resume the position shown in dotted lines in Fig. 5. a Upon reference to Fig. 5 of the drawings, it will be noted that, by the peculiar arrangement of the spirally-arranged cams upon the cylinders, the adjacent ends of said cams overlap each, other and are spaced apart, the adjacent edges of the overlapping cams being )arallel for a short distance which will allow th'ecylinders to rotate a short distance while the carriages are at rest and, during this interval, the endless carrier will have been given an intermittent movement suflicient to advance the bobbins a distance equal to the distance between the. bits. It will also be noted that, by the provision of an apparatus as shown and described, the parts are so arranged as to cause'movements of the machines to be made at predetermined moments to bring the bobbins to be bored into alinement with the bits and securely hold the carrier chain while the carriages carrying the bits are driven forward and continuously rotate through the medium of the swinging belts 53 which are driven from any suitable pulleys not shown.
